Well, time to ask another programming question. 

Is there a nice way using Lattice C to perform a Wait type function
that puts my program to sleep until a given scanline is passed?

Basically, I am using DrawImage to place a small picture on the    
screen and move it around.  I am using WaitTOF() to keep things
moving around at 60Hz, but DrawImage can't finish the draw in time
near the top of the screen (flicker, and random color splotches
depending on what bitplane it has gotten through by then).

I want to avoid assembler for now, but I didn't see a way to 
utilize the copper for this in C in the RKM.

Any clues?

Thanks,
 Joe Peck
